and then rerunning 'make check'. I'm guessing the .lcm files were the old format.

Standalone tests are failing (TestStandaloneInclusions, TestSavingStandalone) but I see that's a WIP.
And I had to intervene manually twice because of stackFileVersion problems, and the debugger popped up on a revDeleteSomethig error.

The tests for saving standalones are failing, apparently because the stackFileVersion is being set to 2.4, and my preferences are set to preserve stack file formats.
This requires manual intervention to allow the test(s) to continue.
Selecting 7.0 seems to be the proper response here.

And yes, I did remove both standalonebuilder/* directories before running the tests.
